Description:
With Thumbnail style update landing in the next few weeks, there is a need to support manually adding borders to images, especially where the image has a white background (such as flags, animations, illustrations, et cetera).
This can currently be accomplished by simply adding the 'border' style in place of thumb. However, this then makes it impossible to add a caption.
There's no reason to avoid setting a caption on bordered images, as far as I can see. If users don't want a caption they can simply leave it out. If you want only alt text, there is support in the syntax for this using the alt parameter.
